Coughing is another early symptom of the flu, states Healthline. Coughing can also be a symptom of other illnesses, but in the early stages of the flu, a person usually doesn't cough up mucus or phlegm. Wheezing usually accompanies a cough that is an early sign of a flu.

In many cases, an early cough may cause a person to develop a sore throat, according to Healthline. In the early stages of the illness, a person's throat may feel scratchy and irritated. Additionally, a person may experience a strange sensation when swallowing. Sometimes the throat simply swells instead of becoming sore.

Early symptoms of the flu may also include gastrointestinal problems, such as nausea, stomach pain, diarrhea and vomiting, according to Healthline. The type of gastrointestinal problem a person experiences depends on the specific strain of the flu a person catches, and these problems are usually more prevalent in young children.
